AdTunes is a mobile advertising platform that utilizes the 10-15 second wait period during incoming phone calls to play advertisements to callers. It aims to generate revenue from this untapped period of high attentiveness by paying subscribers incentives to have ads served to their callers. Advertisers benefit from a low-cost, targeted, and measurable advertising channel. The platform will integrate with telecom networks and mobile operators via APIs to access subscriber data and billing systems. It has the potential to capture a portion of Nigeria's large radio advertising budget by targeting the country's large youth population.
